Research on robots that accompany humans is being continuously studied. The
Pet-Bot provides walking-assistance and object-carrying services without any
specific controls through interaction between the robot and the human in real
time. However, with Pet-Bot, there is a limit to the number of robots a user can
use. If this limit is overcome, the Pet-Bot can provide services in more areas.
Therefore, in this study, we propose a swarm-driving middleware design adopting
the concept of a swarm, which provides effective parallel movement to allow
multiple human-accompanying robots to accomplish a common purpose. The functions
of middleware divide into three parts: a sequence manager for swarm process, a
messaging manager, and a relative-location identification manager. This
middleware processes the sequence of swarm-process of robots in the swarm through
message exchanging using radio frequency (RF) communication of an IEEE 802.15.4
MAC protocol and manages an infrared (IR) communication module identifying
relative location with IR signal strength. The swarm in this study is composed of
the master interacting with the user and the slaves having no interaction with
the user. This composition is intended to control the overall swarm in
synchronization with the user activity, which is difficult to predict. We
evaluate the accuracy of the relative-location estimation using IR communication,
the response time of the slaves to a change in user activity, and the time to
organize a network according to the number of slaves.
